Abstract: An air mixer for an air distribution system for a building includes a set of fixed, substantially parallel partitions arranged in a spaced-apart, side- by--side manner, these partitions forming alternating primary and secondary air passageways. The primary air passageways are open-ended and extend from a front side to a rear side of the mixer. Front end plates extend respectively across front sides of the secondary air passageways and each has elongate edge portions extending along two opposite longitudinal edges thereof. Each elongate edge portion projects beyond the plane defined by an adjacent one of the partitions. Air flow splitters are mounted in the secondary air passageways and each is connected to an adjacent pair of the partitions. These splitters in operation of the mixer turn incoming air flow that enters the secondary air passageways towards the front end plates. Air gaps are formed between the elongate edge portions and front edges of the partitions to enable the air flow in the secondary air passageways to enter the primary passageways where the two air flows are mixed.

Title: Method and apparatus for reducing signal processing requirements for transmitting packet-based data with a modem
Inventor: YAMANO LARRY C
IPC: H04Q11/04
Filed: 1998-05-08
Granted: 2003-07-22
Abstract: A modem and method for operating same. A receiver circuit of the modem is coupled to receive a continuous analog signal from a communication channel. This analog signal includes both packet and idle information. The receiver circuit monitors the analog signal to detect the presence of idle information. Upon detecting idle information, the receiver circuit enters a standby mode in which the processing requirements of the receiver circuit are reduced. A burst mode protocol is also provided, in which packets of digital information are modulated by a transmitter circuit of the modem, thereby converting the packets of digital information into analog signal bursts of discrete duration. These analog signal bursts are transmitted from the transmitter circuit to a telephone line. However, the transmitter circuit does not generate any signals between the analog signal bursts. A receiver circuit monitors the telephone line to detect the analog signal bursts. Upon detecting the presence of the analog signal bursts on the telephone line, the receiver circuit demodulates the analog signal bursts using full processing capabilities of the receiver circuit. However, upon detecting the absence of the analog signal bursts on the telephone line, the demodulating function of the receiver circuit is disabled. The burst mode protocol enables multi-drop and multi-cast operation, as well as reducing required DSP resources.

Abstract: The whirlpool tub includes a rigid tub shell inserted into the opening of a surrounding podium. The tub is to be filled with hot water. A first insulation membrane is installed spacedly around the tub inside the podium, defining a first closed air pocket between the tub and this first insulation membrane. A second insulation membrane is installed spacedly around the first insulation membrane, also inside the podium, defining a second closed air pocket between the first and the second membranes. The first membrane is punctured and hangs loosely from the podium structure, thus allowing limited air circulation between the first and second air pockets. Consequently, positive condensation control is accomplished, preventing same from occurring, in addition to providing thermal and acoustic insulation to the tub. The first membrane comprises an inner reflective metallic foil fixedly mounted on a synthetic felt backing. The second membrane is a mineral wool blanket.

Abstract: A digital signature system includes a data receiver for receiving an electronic document over a network; an encryption key database, and a signature processor in communication with the encryption key database and the data receiver. The encryption key database includes encryption key records, each being associated with a subscriber of the database and identifying an encryption key uniquely associated with the subscriber. The signature processor is configured for receiving an indicator of one of the subscribers and for deriving a digital signature from the received electronic data and the encryption key associated with the one subscriber. Upon receipt of electronic data and an indicator of one of the database subscribers, the digital signature system derives a digital signature from the received electronic data and the encryption key associated with the one database subscriber. Typically, the database subscriber is the originator of the electronic data, and the data originator identifies itself by providing the signature processor with a personal identification number assigned to the data originator. After the digital signature is derived, preferably the digital signature system then transmits the derived digital signature to the data originator.

Abstract: A prosthetic nucleus (30) replacement comprises a solid flattened oval disk. The top surface (32) of the disc is domed, and has a crest that is about three times higher than the crest on the domed bottom surface (34). Both top, and bottom surfaces are therefore convex. A peg (36) extends down from the middle of the bottom domed surface (34), and is used to pin the disc to the lower of two vertebrae it fits between. Metal markers are inserted into the peg (36), and an outside edge of the disc (22) so that radiographs can be used to determine the disc's in situ position. The prosthetic nucleus (30) replacement is surgically implanted into the hollowed out intervertebral space through a flap cut in the natural annulus fibrosis. The lower vertebrae (22) is prepared to receive the peg (36) by clearing the material covering the top of the bone matrix. Bone cement is used around the peg (36) to ensure a tight fit, and immobile attachment of the disc to the lower vertebrae (22).
